Methodical positions are brought in article on prevention of hit of large hard particles in equipment of gas regulating posts. It is offered to provide installation a device on clearing natural gas before each group of gas equipment if in leading to him gas gasmain possible forming hard particles. It is offered also to build in additional filterring elements in design adjusting armature and nodes of account of gas if between them and installation peelings are located connecting pipe lines, in which possible forming hard particles. It is received target function, installing requirements to maximum size of cell filterring element, executed from braided metallic net. Calculations called on according to offered target function, show that under maximum size of hard particles, equal 0.12 mm, approximate maximum size of cell for net of pinpoint accuracy forms 0.08 mm.
